By Rachel LeePeru has expelled two more North Korean diplomats _ following the deportation of the ambassador _ over the North's continued violation of U.N. Security Council resolutions on its nuclear program.Peru's foreign ministry said First Secretary Pak Myong-chol and Third Secretary Ji Hyok had 15 days to leave the Latin American country.The ministry made the announcement after it discovered the envoys were carrying out activities incompatible with their diplomatic duties.North Korea's "continuous" violation of United Nations Security Council resolutions relating to the nuclear program _ which has endangered world peace and security _ also led to the decision, the foreign ministry said. In September, Peru ordered North Korean Ambassador Kim Hak-chol to leave because of Pyongyang's violation of U.N. resolutions on its nuclear and ballistic missile programs.On Sept. 7, Mexican President Enrique Pena Nieto declared North Korean Ambassador Kim Hyong-gil persona non grata and gave him 72 hours to leave the country. The Mexican foreign ministry said the decision was meant to express the country's "absolute rejection" of North Korea's nuclear tests.Spain, Italy and Kuwait also ordered their North Korean ambassadors to leave. Kuwait decided to stop issuing visas to North Koreans.Portugal cut ties with North Korea in July as part of efforts to strengthen pressure on the North to make it come to the dialogue table.Some countries are scaling down their economic ties with Pyongyang. The Philippines, one of the North's top-three trading partners, said Sept. 8 it would suspend trade relations to comply with U.N. resolutions. Thailand has also reportedly cut down on economic exchanges with the North.The U.N. Security Council imposed new sanctions Friday in response to Pyongyang's latest ballistic missile test.The United States-drafted resolution includes measures to slash North Korea's petrol imports by up to 90 percent; that all North Koreans working overseas will have to return home within 24 hours; and a ban on exports of North Korean goods, including machinery.
